Feature: 1. The shell is made of self‑extinguishing material ABS, self‑powered, no external power supply is needed. 2. The action current 0.5/1.5A‑200AAC can be adjusted by the potentiometer, and the LED indicator can conveniently and intuitively indicate the working status. 3. SCR non‑contact electronic switch, no limit on the number of on‑offs, quick response speed. 4. The switch has no limit on the number of on-off times, and the response speed reaches the ms level. 5. Through core structure design, isolation withstand voltage up to 2000V. 6. Hysteresis is less than 1%, can be used under strong magnetic field conditions. 7. The switch has a maximum AC/DC load of 1A at 240VAC, which is a good choice for automated industrial control equipment. 8. Has the advantages of high accuracy, stable performance and long service life.

Product Introduction: SZC03 series AC current induction switch is designed and produced to solve AC current monitoring. It uses the principle of mutual inductance to isolate AC current by inducing AC through-core current, output a normally open or normally closed switching signal, and directly control various automated industrial control equipment Compared with traditional transformer, thermal protectors and other devices, using this device can not only obtain more accurate and timely control effects, but also greatly simplify Design, reduce costs, and greatly improve the overall competitiveness of the product, which can exceed 200% of the rated value.Size: Approx. 70mm / 2.8in62mm / 2.4in 20mm / 0.8in80mm / 3.1in 90mm / 3.5in 25.5mm / 1in3.85mm / 0.2in . Package List: 1 x Current Mutual Inductance Switch
